Implement set

In the core `f1` module you can do something like.

``` javascript
ui.set("someState")
```

Which will force the ui to simply jump/pop to that state and ignore path finding and animation. This could be implemented in `react-f1` by doing something like

``` javascript

```

Start by locating the ReactF1 component and its existing state, path-finding, and animation handling, then compare it with the core f1 ui.set("someState") behavior. Done means the set prop accepts a state and makes the UI jump or pop directly while skipping path finding and animation.
